useful Improvements in Telephone Attachments, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a receiver-holding and hook-operating attachmentfor telephones.

It contemplates, among other objects, the provision of means for holding the receiver in position against the ear of'a person using a telephone and in such a way that free use of both hands will be permitted.

Considerable difliculty has been experienced in the use of telephones by reason of the fact that persons using them are too close up, too far away from, or do not speak directly into the transmitter. It is one of the objects of this invention to remedy these defects by positioning the receiver with relation to the transmitter so that the best results may be obtained.

A further object is so to arrange the attachments and operative parts of the device with relation tothe telephone that it will not detract from or interfere with the normal. and. usual manner of operation, and thus avoid objections made generally to the use of such attachments. I r

The simplicity of this device, its few parts,

the manner of operatively connecting it with the telephone hook, and otherv objects'and advantages, will in part be obvious, and in part be made clear in thedescription which follows. a

Drawings are hereto appended which illustrate two possible embodiments of the invention, and in which:

Figure lis a view inside elevation, showing one form of the device attached to a desk telephone of well-known type: j

Fig. 2is a fragmentary view in front elevation; Fig. 31s a sectional view on l nes 33,

Fig. 8 is a detached view inside elevat1on of a part; Figs. 9,10, 11 and 12 are views in top plan,

vertical section, end elevation, and cross section, respectively, of one of the components; Fig. 13 is a top plan view of another em bodiment and Figs. 14:, 15 and 16 are similar views of slightly modified forms of alternative component parts.

In these drawings, the numeral 1 desig- 1, and an operating hook 5.

The devices which comprise my invention are adapted to be associated with the tele- Phone and may be said to comprise a supporting means 6, a trigger carrying extension bracket 7, and a receiver-supporting arm :8, together with connections and associated components which will be hereinafter described. I I

The supporting means, when used in connection with a telephone of the desk type, comprise preferably a clamping element having cooperating parts 9 and 10 connected at one end, as by a hinge 11. 'At the other end it is provided with a locking means, 12. Intermediate their ends, the cooperating parts'of the clamping means are hollowed or formed so as to embrace thepedestal of a lug 15, on.the portion 12 of the clamping bracket, its other end being threaded for the Y reception of a thumb-screw 16 adapted to bear against a lug 17 carried by the other component'of the clamping member.

Mounted upon a portion 10 of the clampingmember is an arm 19 having at its upper end a reduced'portion 20 and a projection 21. This is adapted to be embraced by a collar 22 having a notch 23 adapted to engage the projection 21, as best seen in Figs. 6 and The collar. 23 is formed on the free end of anangulated extension-bracket24 which has mountedintermediate its ends a trigger 25. This triger; has'at one end an'oflset portion 26 and anextended portion 27, and is mounted intermediate its ends upon a pivot 28 .carried by the extended portionof the angulated arm. The other end of the trigger 25 i p i w th a resili nt means r2 lv 1 as a spring, secured to a knob 31 on the arm and a corresponding projection 32 on the end of the trigger.

The purpose of this trigger is to hold down the hook of the telephone while the receiver is off the hook and is seated in the bracket. To this end, there is provided a projection 33 carried by a collar 34 having a threaded stem' 35 which is adapted to pass through an opening 36 in the hook and Intermediate the ends of these clamping members, there is provided a locking means which constitutes an eye 42 adapted to hold and surround one end of the receiver-supporting-arm 8. Upon this eye, there is mounted a stem 45 threaded at its free end and passing through openings 46 and 47 in the clamping members. A thumb-nut 48, disposed on the threaded end of this stem, is adapted to hold the loop in engagement with the free end of the receiver-supporting-arm and, at the same time, force the clamping members into engagement with the end of the angulated extension arm.

Upon the outer end of the receiver-supporting-arm there is mounted a holding member. This member is preferably in the form of a semi-circular extension hollowed outin the center and having opposed faces 50 and 51 which. permit the insertion therebetween of an extended collar 52 which is usually found upon the end of the receiver.

The receiver-supporting arm may be square (as shown in Fig. 15) or rounded (as shown in Fig. 16), and it has been found desirable, in some instances, to provide it with a bend or offset as at 53, and

best seen in Figs. 15 and 16.v This deflection is for the purpose of holding the receiver in more intimate contact with the ear of the operator when using the telephone.

For use in connection with a telephone of the Wall-type, there is provided a supporting bracket comprising a base 54 adapted to be secured to the Wall or to the backof the telephone in any desirable manner, as by screws 56. Upon this base, there is mounted a support 57, hollowed out internally for the reception of a portion 58 of an angulated extension arm 59. This may be held'in position suitably, as by a screw 60. In this construction, the trigger mechanism is generally mounted upon a projection 61 which is in alinement with the portion 58 of the arm, While the receiver-supportingarm is mounted upon the extended portion 59 in angular relation to portion 58, as be- 2' described a bracing membercomprising a ,clamplng instrumentality. havlng two portions 66 and 67 provided with eyes 68 and adapted to be secured around the pedestal of the telephone as by screws 69 disposed in said eye and adapted to draw said portions together in clamping engagement with the base. Upon one of these members there are mounted extended arms 70 and 71 in spaced. apart angular relation and provided with feet 7 2 adapted to normally rest at the A base level of the, telephone.

In operation, the receiver-supporting arm 8 is adjusted so that, when in use, the operator by pressing his ear against the receiver will be in the proper position with relation to the transmitter most effectively to use the telephone. In this position, it is only necessary to move the trigger toward the base of the telephone, thus permitting the projection 33 to ride up over, the offset portion 26 of the trigger and close the circuit. When the operator is through using the telephone, by pressing down on the hook, the offset portion 26 thereof will ride up over the projection 33 and hold the hook down, opening the circuit and rendering the telephone inoperative.

From the foregoing, it will be apparent that I have provided a convenient and efficient means for maintaining a receiver, of a telephone, in proper relation to the transmitter; and'wherein both hands of the operator are free during thetrans'mission and reception of messages; and which will not interfere with the normal working of the telephone in anyway.

While I have disclosed the invention in the two embodiments herein illustrated, it will be evident that many changes in the construction and general arrangement of the parts may bemade, without departing from the spirit of the invention or sacrificing its chief advantages.

What I claim is 1. A receiver-supporting and hook-operating attachment for telephones, comprising a support adapted to be operatively associated with a telephone, an extension-arm disposed on the support, amounting disposed on the extension-arm and comprising co-acting clamping-members, an eye having a stem passing through the clamping-members, a receiver-supporting member mounted in said eye, means for effecting pressure between the clamping-members, the eye, and the extension-arm, and trigger-mechanism disposed on the arm and adapted normally to engage a hook on the telephone.

2. A receiver-supporting and hook-operating attachment for telephones, comprising a supporting-bracket adapted to be operatively associated with the telephone, an angulated extension-arm disposed on the bracket, a receiver-supporting member mounted on the angulated arm, a trigger mechanism disposed on the arm and adapted normally to engage a hook on the telephone, and means for adjustably supporting the member on the angulated arm and comprising co-acting clamping-members and an eye having a stem passing therethrough and adapted to embrace a portion of the receiver-supporting member and be pressed into engagement therewith.

3. Areceiver-supporting and hook-open ating attachment for telephones, comprising a supporting bracket adapted to be o-peratively associated With the telephone, an angulated extension-arm disposed on the bracket and adjustablehorizontally and vertically with relation to said telephone, a receiver-supporting member mounted on the arm, means for locking the member to the arm comprising co-acting clamping-memhers adapted to embrace a portion of the arm, and an eye adapted to embrace a portion of the receiver-supporting member and having a stem passing through the clamping members, and trigger-mechanism disposed on the arm and adapted normally to engage a hook on the telephone.

In testimony whereof I affiX my signature.

JOHN J. OONVERY.
